Description

TECHNICAL FIELD

[0001] The following disclosure relates to a door connector assembly. BACKGROUND

[0002] A connector is an electrical component that connects or disconnects an electrical connection. Connectors are used in various mechatronic devices such as automobiles or home appliances to achieve electrical and / or physical connection between a plurality of electronic components.

[0003] For example, when a connector is installed between a vehicle body of a vehicle door, an operator can have difficulty in fastening the connector since the connector needs to be installed in a narrow space. Accordingly, various studies have been made on a structure for improving convenience in fastening the connector or a structure for precisely fastening the connector.

[0004] The above description is information obtained in the process of conceiving the present disclosure or information possessed at that time, and does not necessarily have to be a technology known before the filing of the present application. SUMMARY

[0005] Technical solutions to problems

[0006] A door connector assembly according to an embodiment can include a cover including a flange, a cover body extending from the flange in a direction and internally supportable of a first cable, and an insertion through-wall extending from the flange in another direction and penetratingly inserted into a mounting hole of a panel, a plug supportable of a second cable fastened to the first cable, and a lever rotatably installed to the plug and fixed to the cover such that the plug is not separated from the cover when the plug is fastened to the cover. For example, the insertion through-wall can include a gap prevention wall having an outer side edge shape corresponding to an edge of the mounting hole and for preventing the cover from flowing in a direction parallel to the panel, and a plug coupling wall extending from the gap prevention wall in the other direction, having a shape stepped in an inner side direction from the gap prevention wall, and coupled to the plug.

[0007] According to an embodiment, the cover can further include an elastic hook protruding from the gap prevention wall in an outer side direction and bendable inward from the gap prevention wall, and a retreat space providing a retreat space based on a fastening direction of the plug and the cover at a position where the elastic hook does not deviate from the outer side edge shape of the gap prevention wall.

[0008] According to an embodiment, the cover can further include a main protrusion protruding outward from the plug coupling wall and configured to be moved along a main guide formed in the lever by an operator during rotation of the lever, thereby allowing the plug to be inserted in the direction of the cover. For example, the main protrusion can not deviate from the outer edge shape of the gap prevention wall based on the fastening direction.

[0009] According to an embodiment, the elastic hook and the main protrusion can overlap each other based on the fastening direction. For example, the retreat space can have a shape that is communicated with the outside in a direction perpendicular to the protruding direction of the elastic hook and the fastening direction.

[0010] According to an embodiment, the elastic hook and the main protrusion can not overlap each other based on the fastening direction.

[0011] According to an embodiment, when the elastic hook is a first elastic hook, the cover can further include a second elastic hook protruding outward from the gap prevention wall and bendable inward from the gap prevention wall. For example, the first elastic hook and the second elastic hook can be formed in a point-symmetrical position based on the center of the cover when viewed from the fastening direction.

[0012] According to an embodiment, the door connector assembly can further include a faceplate seal mounted between the flange and the faceplate.

[0013] According to an embodiment, the cover can further include a faceplate position assurance protrusion spaced apart from the flange by a predetermined distance and protruding outward from the gap prevention wall.

[0014] According to an embodiment, the cover can further include a cable position assurance member inserted into the cover in a direction perpendicular to the one direction and configured to prevent the second cable from being pushed out during fastening of the cover and the plug.

[0015] According to an embodiment, the door connector assembly can further include an intermediate seal configured to prevent foreign substances from entering between the plug and the cover.

[0016] According to an embodiment, the plug can further include a plug body configured to support the second cable and to be inserted into the inside of the plug coupling wall, and a plug housing configured to wrap at least a portion of the outside of the plug body and to be coupled to the outside of the plug coupling wall, and to have a rotation shaft of the lever formed in an inner wall thereof. For example, the intermediate seal can be positioned between the plug body and the plug coupling wall when the cover is coupled to the plug.

[0017] According to an embodiment, the door connector assembly can further include a plug seal for preventing foreign substances from entering an end of the plug.

[0018] According to an embodiment, the cover can further include a sub-protrusion protruding outward from the plug coupling wall and configured to be interfered by the lever when an operator rotates the lever in an initial process of inserting the plug into the cover, thereby rotating the lever in a direction away from the cover, and a main protrusion protruding outward from the plug coupling wall and configured to move along a main guide formed in the lever when the operator rotates the lever in a direction close to the cover after the initial process is completed, thereby inserting the plug in a direction toward the cover. For example, the main protrusion and the sub-protrusion do not deviate from the shape of the outer edge of the gap preventing wall based on the fastening direction of the plug and the cover.

[0037] Reference will now be made in detail embodiments of the application, examples of which are illustrated in the accompanying drawings. Figures 1 to 4 A door connector assembly 1 according to an embodiment can include a plug 11, a cover 12, and a lever 14. At least a portion of the cover 12 can be positioned in an inner space based on a panel P (e.g., a panel of a vehicle). The cover 12 can support a first cable C1 inside a first object body B (e.g., a body of a vehicle), and an insertion through-wall 123 of the cover 12 can be exposed to the outside through a mounting hole H formed in the panel P of the first object body B. The plug 11 can be positioned in an outer space opposite the cover 12, based on the panel P. The plug 11 can support a second cable C2 inside a second object body D (e.g., a door of a vehicle), and can be positioned in a space between the first object body B and the second object body D. In other words, the cover 12 can be fastened to the plug 11 from an opposite direction, with the panel P positioned between the cover 12 and the plug 11, such that the first cable C1 can be electrically connected to the second cable C2.

[0038] The plug 11 supports the second cable C2 mounted through the plug 11, and can be detachably connected to the cover 12. When the plug 11 is normally coupled to the cover 12, the second cable C2 can be connected to the first cable C1 mounted in the cover 12. The plug 11 can include a plug body 111 (which can be inserted into an inside of the insertion through-wall 123 of the cover 12 and can support the second cable C2), a plug housing 112, and a rotation shaft 113.

[0039] The plug housing 112 has a shape that wraps at least a portion of an outside of the plug body 111, and can be coupled to an outside of the insertion through-wall 123. In other words, the insertion through-wall 123 can be inserted into a space between the plug housing 112 and the plug body 111. For example, the plug housing 112 can reduce an impact force applied to the lever 14 from the outside by having a shape that wraps at least a portion of the lever 14.

[0040] The rotation shaft 113 is formed on an inner wall of the plug housing 112, and rotatably supports the lever 14. For example, the rotation shaft 113 can have a shape that protrudes from the inner wall of the plug housing 112 toward the plug body 111.

[0041] The cover 12 supports a first cable C1 mounted through the cover 12 and can be configured to be detachably connected to the plug 11. The cover 12 may include a flange 121 that may be located on the rear of the panel P, extending from the flange 121 along a direction (e.g., Figure 2 The cover 122, which extends from the flange 121 in the upper direction and supports the first cable C1 internally, extends from the flange 121 in another direction (e.g., Figure 2 An insertion through-wall 123 extends (towards the lower side) and is inserted through the mounting hole H of the through-panel P, and an elastic hook 124 protrudes outward from the insertion through-wall 123 and can be bent inward from the insertion through-wall 123.

[0042] The insertion through wall 123 can be integrally formed with the flange 121. The end of the insertion through wall 123, i.e., the remaining portion except for the inlet portion coupled to the plug body 111 (the side wall of the insertion through wall 123), can have a closed structure from the outside. In this structure, when the plug 11 is coupled to the cover 12, foreign objects can be prevented from flowing in from the side of the insertion through wall 123. The insertion through wall 123 may include a gap prevention wall 1231 and a plug coupling wall 1232.

[0043] The gap-prevention wall 1231, by having an outer edge shape corresponding to the edge of the mounting hole H, can prevent the cover 12 from flowing in a direction parallel to the panel P. Furthermore, the gap-prevention wall 1231, together with the panel seal S1, can prevent foreign objects from entering the space between the mounting hole H of the panel P and the cover 12 from the outside.

[0044] The plug coupling wall 1232 prevents the gap prevention wall 1231 from moving in the other direction (e.g., Figure 2 The plug coupling wall 1232 extends (in the upper direction) and can couple with the plug 11. The plug coupling wall 1232 can have a stepped shape extending inward from the gap prevention wall 1231. With this shape, the interference of the plug coupling wall 1232 on the installation can be reduced when the cover 12 is installed on the panel P. In addition, since a free space can be ensured between the plug coupling wall 1232 and the gap prevention wall 1231, the main protrusion 126, the auxiliary protrusion 127 and the fastening protrusion 130 can be formed in this free space. With this structure, the door connector assembly 1 can be assembled in a lever manner rather than a sliding manner, thereby minimizing the gap between the cover 12 and the mounting hole H of the panel P.

[0045] The plug coupling wall 1232, the gap prevention wall 1231, and the flange 121 can be integrally formed by injection molding or other methods, thereby reducing the entry of foreign objects from the outside into the internal space of the cover 12.

[0046] The mounting hole H of panel P can be hooked by the end of resilient hook 124 to prevent panel P from detaching from cover 12. For example, as Figure 4As shown, the elastic hook 124 can be retracted into a retreat space 125 formed in the cover 12. For example, the retreat space 125 can be formed large enough so that the elastic hook 124 can be retracted to a position not deviating from the outer side edge shape of the gap prevention wall 1231 based on the fastening direction (e.g., the up-down direction) of the plug 11 and the cover 12. With this structure, the gap prevention wall 1231 can pass through the mounting hole H of the panel P, and after the gap prevention wall 1231 passes through the mounting hole H, the gap between the gap prevention wall 1231 and the mounting hole H can be minimized. Figure 4

[0047] The cover 12 can further include a main protrusion 126, an auxiliary protrusion 127, a cable position assurance member 128, and a fastening protrusion 130. When the plug 11 and the cover 12 are fastened to each other, the main protrusion 126 and the auxiliary protrusion 127 are interfered by the lever 14, thereby assisting the assembly between the plug 11 and the cover 12. The interaction between the main protrusion 126, the auxiliary protrusion 127, and the lever 14 can be referred to the description of the main protrusion 126, the auxiliary protrusion 127, and the lever 14 of the plug 11. Figures 11 to 13 .

[0048] The main protrusion 126 can protrude outward from the plug coupling wall 1232. For example, based on the fastening direction (e.g., the up-down direction), the main protrusion 126 can be formed not to deviate from the outer side edge shape of the gap prevention wall 1231. Figure 2

[0049] The auxiliary protrusion 127 can protrude outward from the plug coupling wall 1232. For example, based on the fastening direction, the main protrusion 126 can be formed not to deviate from the outer side edge shape of the gap prevention wall 1231.

[0050] The cable position assurance member 128 can be inserted into the cover body 122 in a direction perpendicular to the insertion direction of the second cable C2 into the cover body 122 (e.g., the up-down direction). The cable position assurance member 128 can be installed in the cover body 122 when the second cable C2 is inserted into the cover body 122. At least a portion of the cable position assurance member 128 can prevent the second cable C2 from being pushed out when the plug 11 is fastened to the cover 12 by supporting the rear end of the terminal of the second cable C2. Figure 2 The fastening protrusion 130 is a portion that is fastened to the lever 14 when the plug 11 and the cover 12 are fastened to each other, and can prevent the plug 11 from being separated from the cover 12. For example, the fastening protrusion 130 can protrude outward from the plug coupling wall 1232. The fastening protrusion 130, for example, the main protrusion 126, can be formed not to deviate from the outer side edge shape of the gap prevention wall 1231 based on the fastening direction (e.g., the up-down direction).

[0051] Figure 2

[0052] ​​​​The lever 14 is rotatably installed with respect to the plug 11 (e.g., the rotation shaft 113), and can be fixed to the cover 12 so that the plug 11 is not separated from the cover 12 when the plug 11 is fastened to the cover 12. For example, the lever 14 can be set to a state of being temporarily fastened to the plug 11 before the plug 11 is fastened to the cover 12. For example, the position of the lever 14 when the plug 11 is completely fastened to the cover 12 can be the same as the position of the lever 14 before the plug 11 is fastened to the cover 12. The lever 12 can include a lever body 141, a lever cover 142, and a lever arm 143.

[0053] The lever body 141 is rotatably installed on the rotation shaft 113. As described below, the lever body 141 can be formed with a main guide 6411 and an auxiliary guide 6412. The main guide 6411 and the auxiliary guide 6412 can be engaged with the main protrusion 126 and the auxiliary protrusion 127, respectively, to help fasten the plug 11 and the cover 12. For example, in order to stably rotate the lever 14, a pair of lever bodies 141 can be installed on both sides of the plug 11.

[0054] The lever cover 142 can connect the pair of lever bodies 141 to each other so that the pair of lever bodies 141 can be connected to each other and rotate together. For example, an operator can assemble the plug 11 and the cover 12 by rotating the lever 14 while holding the lever cover 142.

[0055] When the fastening of the plug 11 and the cover 12 is completed, the lever arm 143 can be fastened to the fastening protrusion 130. For example, the lever arm 143 can be formed on the lever cover 142, but is not limited thereto.

[0056] Figure 5 A sectional view of a door connector assembly 1 according to an embodiment.

[0057] Referring to Figure 5 The door connector assembly 1 according to an embodiment can include (i) a panel seal S1 installed between the flange 121 and the panel P, (ii) a plug seal S2 for preventing foreign substances from entering the end of the plug 11, and (iii) an intermediate seal S3 for preventing foreign substances from entering between the plug 11 and the cover 12. For example, each of the seals can be formed of a flexible waterproof material (e.g., rubber, etc.).

[0058] As shown, the panel P can be positioned between the elastic hook 124 and the panel seal S1, and can be stably fastened to the panel P by the panel seal S1 being pressed by the cover 12. By the panel seal S1, foreign substances can be prevented from entering between the flange 121 and the panel P.

[0059] The plug seal S2 can wrap the end of the plug 11 into which the first cable C1 is inserted. The plug seal S2 can have a shape that wraps the end of the plug 11 and the first cable C1 connected to the plug 11 together.

[0060] When the cover 12 is coupled with the plug 11, the intermediate seal S3 can be located between the plug body 111 and the plug coupling wall 1232. Even if foreign substances (e.g., water, etc.) enter between the insertion through wall 123 and the plug housing 112, such a structure can reduce the influence thereof on the electronic elements in the inner space of the insertion through wall 123. For example, the intermediate seal S3 can be formed along the outer circumference of the plug coupling wall 1232, but is not limited thereto. For example, the intermediate seal S3 can also be formed along the inner circumference of the plug housing 112.

[0061] The elements included in any one of the embodiments below and elements having the same function will be described using the same name in other embodiments. Unless otherwise specified, the description described in any one of the embodiments can be applied to other embodiments, and specific description will be omitted in the overlapping range. For example, referring to Figures 1 to 5 The embodiments described can be applied to Figure 6 and the embodiments described below, and vice versa.

[0062] Figure 6 To show a perspective view and a cross-sectional view of a portion of a cover according to an embodiment.

[0063] Referring to Figure 6 , the cover 22 according to an embodiment can include a flange 121, an insertion through wall 123, an elastic hook 124, a retreat space 225, and a main protrusion 126. The insertion through wall 123 can include a gap prevention wall 1231 and a plug coupling wall 1232.

[0064] The elastic hook 124 is a portion for preventing the cover 22 from being separated from the panel (P, see Figure 3 ) and, for example, it can be advantageous to install the elastic hook 124 at a central position of the side surface of the cover 22 to balance the distribution of force. The main protrusion 126 is a portion that supports force by interaction with a lever (14, see Figure 2 ) during fastening of the plug (11, see Figure 2 ) and the cover 22, and, for example, it can be advantageous to install the main protrusion 126 at a central position of the side surface of the cover 22 to balance the distribution of force. Accordingly, the elastic hook 124 and the main protrusion 126 can be formed at positions overlapping each other, based on the fastening direction (e.g., the up-down direction of Figure 6 ) of the plug 11 and the cover 22.

[0065] Because the aforementioned structure causes an undercut, injection molding may be difficult. Considering this difficulty, for example, the backlash space 225 can be formed in the fastening direction with the plug 11 and the cover 22 (hereinafter referred to as the first direction) (e.g., Figure 6 The vertical direction) and the protruding direction of the elastic hook 124 (hereinafter referred to as the second direction) (for example, Figure 6 The direction perpendicular to the left and right directions (hereinafter referred to as the third direction) (for example, Figure 6 The shape communicates with the outside in the direction from the ground. With this shape, injection molding can be performed using a sliding core that can slide in a third direction, thereby forming elastic hooks 124 and main protrusions 126 at overlapping positions.

[0066] Figure 7 This is a schematic diagram showing the side of a lid according to one embodiment. Figure 8 This is a schematic diagram showing the top of a lid according to one embodiment.

[0067] Reference Figure 7 and Figure 8 According to one embodiment, the cover 32 may include a flange 121, an insertion through wall 123, an elastic hook 324, a retraction space 325, and a main protrusion 126. The insertion through wall 123 may include a gap prevention wall 1231 and a plug coupling wall 1232.

[0068] According to one embodiment, the resilient hook 324 and the main protrusion 126 can be based on the fastening direction of the plug 11 and the cover 32 (e.g., Figure 7 The top and bottom directions are formed so that they do not overlap. For example, the main protrusion 126 may be located at the center of the side of the cover 32, while the resilient hook 324 may be located on a portion offset to one side relative to the center of the side of the cover 32.

[0069] With this structure, a recessed space 325 can be formed in the direction in which the insertion through-wall 123 extends from the flange 121. Therefore, since the cover 32 can be formed by injection molding using the same core as the core forming the insertion through-wall 123, manufacturing costs and difficulty can be reduced.

[0070] For example, in order to securely fasten the cover 32 to the panel (P, see Figure 3 Hooks can be provided on both sides of the cover 32 relative to the center O. In other words, a second elastic hook 324 can be provided on the side opposite to the first elastic hook 324 based on the center O of the cover 32. Each elastic hook 324 can protrude outward from the gap prevention wall 1231 and can be bent inward from the gap prevention wall 1231.

[0071] For example, from the fastening direction of the plug 11 and the cover 32 (e.g.,Figure 7 The first elastic hook 324 and the second elastic hook 324 can be formed in a point-symmetrical position based on the center O of the cover 32 when viewed in the up-and-down direction of the cover 32. With this configuration, the support force of the cover 32 on the panel P can be uniform even if there is a deviation in the position of the elastic hook 324.

[0072] Figure 9 A perspective view of a cover according to an embodiment and an enlarged sectional view of a portion of the cover.

[0073] Referring to Figure 9 , the cover 42 according to an embodiment can include a flange 121, an insertion-through wall 123, an elastic hook 424, a retreat space 425, and a main protrusion 126. The insertion-through wall 123 can include a gap prevention wall 1231 and a plug coupling wall 1232.

[0074] According to an embodiment, the elastic hook 424 and the main protrusion 126 can be formed not to overlap each other based on a fastening direction of the plug 11 and the cover 42 (e.g., an up-and-down direction of the cover 42). Figure 9 For example, the main protrusion 126 can be located at the center of the side surface of the cover 42, and the elastic hook 424 can be located at a portion deviated from the center of the cover.

[0075] For example, a plurality of elastic hooks 424 can be arranged at both sides of the cover 42. The plurality of elastic hooks 424 can be located at opposite sides of an imaginary line passing through the main protrusion 126 and parallel to the above-described fastening direction, and can be positioned equidistantly from the above-described imaginary line. With this configuration, the support force of the cover 42 on the panel P can be uniformized. For example, a plurality of elastic hooks 424 having the same arrangement can also be provided at a side opposite to the side surface of the cover 42 as shown. Figure 9

[0076] Figure 10 A perspective view of a cover according to an embodiment and an enlarged sectional view of a portion of the cover.

[0077] Referring to Figure 10 , the cover 52 according to an embodiment can include a flange 121, a cover body 122, an insertion-through wall 123, an elastic hook 124, a main protrusion 126, an auxiliary protrusion 127, a panel position guarantee protrusion 529, and a fastening protrusion 130. The insertion-through wall 123 can include a gap prevention wall 1231 and a plug coupling wall 1232.

[0078] The panel position guarantee protrusion 529 can be spaced apart from the flange 121 by a set distance, and can protrude outward from the gap prevention wall 1231. For example, a plurality of panel position guarantee protrusions 529 can be spaced apart from the flange 121 by equal set distances. The panel position guarantee protrusion 529 can be formed not to overlap the main protrusion 126 based on a fastening direction of the plug and the cover 52 (e.g., an up-and-down direction of the cover 52). Figure 10 ​The vertical direction) is formed between the elastic hook 124 and the flange 121. The panel position ensures that the protrusion 529 can be formed to prevent the wall 1231 from protruding outward from the gap formed by the mounting hole H corresponding to the panel P, thereby preventing the cover 52 from being fastened beyond a certain distance when it is fastened to the mounting hole H of the panel P. For example, as Figure 10 As shown in the enlarged cross-sectional view, when the cover 52 is fastened to the panel P, a certain distance may be formed between the panel P and the cover 52. This structure allows for the control of the compression ratio of the panel seal S1. Furthermore, the panel position-ensuring protrusion 529 reduces the upward displacement of the panel seal S1 from the gap prevention wall 1231 and prevents it from deviating from its designed position. In other words, the panel seal S1 can be stably fixed in its designed position by the panel position-ensuring protrusion 529. Therefore, during the transportation of the cover 52 with the panel seal S1 installed or when the cover 52 is installed on the panel P, problems such as deformation or damage to the panel seal S1 can be reduced.

[0079] Figures 11 to 13 This is a cross-sectional view of the process of fastening a door connector assembly according to an embodiment.

[0080] Reference Figures 11 to 13 According to one embodiment, the door connector assembly 6 may include a plug 61, a cover 62, and a lever 64. The plug 61 may include a plug body 611, a plug housing 612, and a rotating shaft 613. The cover 62 may include a flange 621, a cover body 622, an insertion through wall 623, a main protrusion 626, an auxiliary protrusion 627, and a fastening protrusion 630. The insertion through wall 623 may include a gap prevention wall 6231 and a plug coupling wall 6232. The lever 62 may include a lever body 641, a lever cover 642, and a lever arm 643. The lever body 641 may include a main guide 6411 and an auxiliary guide 6412.

[0081] Figures 11 to 13 The process of fastening the plug 61 and the cover 62 together is shown in sequence.

[0082] like Figure 11 As shown, the main protrusion 626 and the auxiliary protrusion 627 can protrude outward from the plug coupling wall 6232. First, the auxiliary protrusion 627 can be configured such that when the operator initially inserts the plug 61 into the cover 62, it is interfered with by the lever 64, causing the lever 64 to move in a direction away from the cover 62 (e.g., ...). Figure 11 (Counterclockwise) Rotation. Since the lever body 641 is constrained by the rotation axis 613 relative to the plug 61, the lever body 641 can rotate relative to the rotation axis 613 by the vertical force generated by the auxiliary protrusion 627, depending on the distance the plug 61 is inserted into the cover 62.

[0083] Figure 12The state shown in FIG. 64 can become the maximum opening state. The auxiliary guide 6412 is a groove formed on the inner wall of the lever body 641, and one end portion of the auxiliary guide 6412 can be formed to face the auxiliary protrusion 627 in the maximum opening state. Further, the main guide 6411 is a groove formed on the inner wall of the lever body 641, and one end portion of the main guide 6411 can be formed to face the main protrusion 626 in the maximum opening state. In this state, if the plug 61 continues to enter the cover 62, as shown in FIG. 65, the auxiliary protrusion 627 and the main protrusion 626 can enter the auxiliary guide 6412 and the main guide 6411, respectively. Figure 12 As shown in FIG. 66, the main protrusion 626 and the auxiliary protrusion 627 can be formed to be separated from the main guide 6411 and the auxiliary guide 6412, respectively, in the initial process completion state.

[0084] As shown in FIG. 67, when the operator rotates the lever 64 in the direction approaching the cover 62 (for example, the clockwise direction of Figure 12 As shown in FIG. 68, when the operator rotates the lever 64 in the direction approaching the cover 62 (for example, the clockwise direction of Figure 13 the main protrusion 626 moves along the main guide 6411 formed in the lever 64, and thus the plug 61 can be inserted into the cover 62. For example, as shown in FIG. 69, the shape of the main guide 6411 can be formed such that the portion of the main guide 6411 contacting the main protrusion 626 becomes closer to the rotation shaft 613 when the lever 64 is rotated in the tightening direction. By this shape, the operator can more easily tighten the plug 61 to the cover 62 by using the lever 64, rather than pressing the plug 61 to the cover 62, and can tighten the plug 61 to the cover 62 as shown in FIG. 70. Figure 13 For example, the lever arm 643 can have a hook shape hooked by the tightening protrusion 630, and can reduce the rotation of the lever 64 in the separation direction (for example, the counterclockwise direction of Figure 13 For example, the lever arm 643 can have a hook shape hooked by the tightening protrusion 630, and can reduce the rotation of the lever 64 in the separation direction (for example, the counterclockwise direction of
